It's Really Hot In The Room

Husband said that the last few days was very hot inside the room. I could understand about that since the weather was also hot here. On top of that, our room is in the second floor, and the window of the room get direct sun light every day. That's why the room become very hot during the day time. If it is possible, I would like to find roller blinds in the store that I can put on the window to cover it. I hope that could be help a little bit to protect the room from the direct sun light that come inside through the window every day.
